Drawing markup
Upload DWG, DXF or PDF; Santix splits multi-sheet files on its own CAD server and reads sheet number, title and scale from the title block, even for sheets drawn side by side in model space. Drop one of six pin types (task, defect, request for information, observation, safety, revision request) with photos, voice notes or video, an assignee, a due date and a comment thread. Subcontractors see only their own pins. Drawing markup
Room data sheets
Rooms are suggested from tags and boundaries in the drawing and approved by the architect or the project team. Tap a room for net area, perimeter, wall and ceiling area, clear height and level, floor, skirting, wall and ceiling finishes, and doors and windows, each value labelled with its source. The architect's room schedule is matched from Excel or PDF text. Room data sheets
Revision tracking
Field engineer raises, site manager approves, architect answers with a note or a new sheet version. Pins move to the new version by drawing coordinates, and versions can be overlaid. Revision tracking
Progress tracking
Crews draw finished areas over a room on the drawing, or mark the whole room. Percentages use the right quantity for each work item: floor area for tiling, wall area net of openings for paint, perimeter for skirting, a count for fixtures. Room progress rolls up to tasks, the schedule and the project overview. Progress tracking
Offline work
Screens read from a local database; entries sync when the connection returns, drawings can be downloaded in advance and conflicts are shown, not overwritten. Offline field app

Schedule and Gantt
Tasks with FS, SS, FF and SF dependencies and lags, milestones and a work calendar; Santix computes the critical path and total float. MS Project XML and Primavera P6 XER import. Gantt on iPad, a list on the phone. Schedule and Gantt
Progress payments and budget
Budget by item code and subcontractor, imported from an Excel estimate. Cumulative hakediş with retention, advance recovery, withholding tax, stamp duty, penalties and VAT withholding on separate lines; TL, USD and EUR converted at the central bank rate of the date; approval by amount. Progress payments and budget
Bid comparison
Line-by-line comparison with the best value per row highlighted and a weighted score, price 60 % by default. The chosen bid flows to the budget and the contract. Bid comparison
Contract templates
Subcontract templates for 40 trades, filled through a four-step wizard with warnings on critical points, a PDF draft and reminders for payment, bond, acceptance, warranty and insurance dates. Not legal advice. Contract templates
Document tracking
More than 20 document types tracked with their validity; scan with the camera, check what was read, and get reminders 30, 14, 7 and 1 day before expiry. Document tracking
Team and data
Site management overview
The project overview screen, how one issue moves from a pin to an approved payment, a typical week and what Santix does not do. Site management
Team and invites
8-character, single-use invite codes valid for 14 days carry the role and the subcontractor's firm; seats are enforced in the database; budget visibility per role is none, summary or full; notifications go only to the people concerned. Team and invites
Roles and permissions
Eight roles, enforced in the database; subcontractors see only their own work. Roles
AI assistance
Suggestions in six places: layer classification, room schedule matching, Excel columns, document reading, contract drafting and bid summaries. Nothing is saved without approval and no drawing geometry is sent. Web price research is not available yet. AI assistance
Security
Data stored and drawings processed in Frankfurt (EU); no ads, tracking or location collection. Security
How do the modules connect?
| From | To | What flows |
|---|---|---|
| Drawing | Rooms | Room outlines, area, perimeter, level and finish texts |
| Room data | Progress | Work item quantity: floor area, wall area, perimeter |
| Progress | Schedule and overview | Task and project percentages |
| Pin | Revisions | A revision request pin enters the approval flow |
| Purchasing | Budget and contract | The chosen bid's lines and firm |
| Contract | Budget and reminders | Retention, advance, payment period, key dates |
| Team | Every module | Who sees and approves what |
Which module should a site start with?
- Create the project and upload current drawings as DWG, DXF or PDF; the architect approves rooms and layers in the review screen.
- Invite the team with codes: site manager and engineers first, then the architect and subcontractors.
- Start on site with pins: snag lists, requests for information and safety notes build up on the drawing from week one.
- Import the schedule from MS Project or Primavera; once progress marks are linked to tasks, the Gantt updates itself.
- Import the Excel estimate into the budget, attach signed subcontracts and expiring documents, and run the next progress payment in Santix.
Santix runs on iPhone and iPad with a Turkish interface, is coming soon to the App Store with TestFlight early access, and Android is in preparation. See pricing.
